widget: make sure to check all children for allocation needs

GtkWidget uses gtk_container_foreach() to iterate over children and
check whether they need their allocation reset.
However, that leaves out internal children, such as scrollbars of a
GtkScrolledWindow. Use gtk_container_forall() instead.
